Eagle EMS
Yes, the Eagle EMS runs great. I have about 115 hours on mine, and loving how great it runs. I get in and start up, and it just runs. I fly in and out of high elevation airports much of the time, and the automated leaning works like a charm. I only touch the electronic leaning when flying distances at cruise. In that case, my IO-320 is running around 2,400 RPM, 6.5 gph. and averages about 140knot true. I can go faster, but I like running with the lower gph.
My initial start up was a bit of a challenge. I had a couple of things that had to be worked through before the first flight. The support staff at Precision was helpful, and we tweaked the items that needed to be addressed. Since my first flight, I have only had a great running engine. Love mine, and would not hesitate to buy one again.
